Eyingozi radiation kunye neempawu zayo

Yelanga imitha - na radiation magnetic, ngamaza apho iyahluka ukusuka emdeni emdeni spectrum nemisonto lwe-X-reyi. Kubalulekile ukuphawula ukuba ukukhankanywa lokuqala le nto zavela kwinkulungwane weshumi elinesithathu. Kwaba ngoko awathi zobulumko Indian kwiincwadi zabo wachaza umoya apho imitha violet equkethwe, ayibonakali ngeliso lenyama.

Ngenkulungwane ye-17 emva kwexesha, xa spectrum infrared ibonakele, izazinzulu ehlabathini lonke Nowuthabatha ukufundwa kwemitha ekupheleni malunga spectrum ukukhanya. Yilaa nto yafunyanwa ngayo kuqala kwaye zihlolwa yelanga. Ngowe-1801, I. W. Ritter wafumanisa ukuba oxide yesilivere mnyama ngokukhawuleza xa zibethwa ukukhanya ongabonakaliyo, ukubayinxalenye violet yinxalenye zazo.

Malunga nelo xesha, izazinzulu ziye kufika kwisigqibo bathi ukukhanya kwakhiwa zizahlulo ezithathu ezahlukeneyo. Oku kubizwa ngokuba yi-ukukhanya ebonakalayo (okanye inxalenye ekhulisa), imitha yobushushu kunye ultraviolet (yona iyafana reductive). Kwixesha elizayo, abasebenzi uphando ngenkuthalo uphando imiphumela ultraviolet radiation kwi eziphilayo, kwakunye nendima yayo indalo.

Eyingozi radiation: iimpawu kunye nokubekwa

Ukuza kuthi ga ngoku, le yelanga eyingozi ukuba zohlulwa ngokwendidi ezintathu eziphambili, nganye eneyazo uneempawu zawo:

• UV-C, ezaziwa kakhulu ngokuqhelekileyo phantsi igama radiation gamma. Kufuneka ngoko nangoko kuqatshelwe ukuba iyingozi kakhulu impilo emzimbeni womntu. Ngethamsanqa, radiation loo ako phantse ngokupheleleyo ioksijini, ozone kunye nomphunga wamanzi ibhola naxa edlula umoya ehlabathini.
• UV-B - olunye uhlobo imitha, apho wafunda phantse ngokupheleleyo irhasi imvulophu woMhlaba. Zifika kumphezulu ayikho ekhulwini ngaphezu kweshumi. Hi ndlela leyi, phantsi kwempembelelo ezi reyi kwenzeka ekuvelisweni yolusu kwabantu bala lintsundu.

• UV-A. Olu hlobo reyi uza phantse ngokupheleleyo kumphezulu umhlaba kunye phantse non-yingozi ukuba izinto eziphilayo. exposure elide kubangela ukuguga olukhawulezisiweyo kwesikhumba.

Yona iipropati, kuba ekuqaleni kufanele kuphawulwe ukuba wemitha ayibonakali ngeliso lenyama. Ngaphezu koko, iye reactivity eliphezulu kwaye ngunobangela basabele ngeendlela ezahlukahlukeneyo zendalo. High lamanani eyingozi ilifa iipropati antibacterial. Kakade ke, asimele silibale ukuba iingedosi ezincinane, oku kunempembelelo entle emzimbeni womntu.

ukukhanya yelanga kunye nempembelelo yawo emzimbeni womntu

Ngoko nangoko Kukwabalulekile ukuqaphela ukuba yelanga ngqo eyingozi igalelo ekwakhiweni yabantu eluswini vitamin E, nto leyo inika calcium ukutya kwesiqhelo bone zikwimeko entle. Ukongeza, imitha yalo spectrum inoxanduva izingqisho zebhayoloji le esiphilayo. Oku kubonakaliswa ukuba ukukhanya yelanga kwandisa amanqanaba igazi ebizwa ngokuba "hormone Yomelela", nto leyo eqinisekisa ukuba urhulumente eziqhelekileyo ngokweemvakalelo.

Ngelishwa, akukho luncedo yaye kuyimfuneko kuphela ngeedosi ezincinane yiultraviolet ukukhanya. Too sesichengeni lukhulu kwezi imitha kubangela nomkhwezeli. Umzekelo, ukuba sesichengeni ixesha elide ekukhanyeni yelanga eluswini ibalekisa wokwaluphala, kwaye kwezinye iimeko, ibangela kunye nokutsha. Ngamanye amaxesha radiation kubangela ukuguquka iiseli, ezinokukwazi zingaphumela ithumba.

Ukwanda ultraviolet radiation kuchaphazela ngokungalunganga retina iliso, ebangela zokutsha. Ngenxa yoko, ngelo xesha sunny kufuneka nje ukuba usebenzise iindondo ezikhethekileyo zokhuselo.
